We’re In It For Patients

Our colleagues reflect on the patients and their families who inspire our work and keep us in it for good, for those we know personally, those we’ve connected with as part of our work and those we may never meet.  

Each and every story is a powerful reminder of why the work we do to bring new medicines to people with serious diseases is so important, no matter how long it takes or how difficult the journey.
